Application filed January 11, 1913. Serial No, 741,386

To Q77 ifi/7mmi muy @021.60771 lle it known iliat we; MARY. Ci/V. l'n'zm and (limi-urns il. Giovi-nn citizens oi' the linitid .idiotest residing;` at 'i'gloustomy in the t'oiisuininf turnace in which. the refuse may be consu4 lilith die above and other objects in View.

as iv'll lien'iore specifically set forth in detail hereinafter; the invention has paiticular re.- ation to certain novelfeatiu'es of constrain 'tion and operation, an example ot'uhich is given in Ythis speeilieation and illustrated in the accompanying drawings wherein Figure 1 is a side elevation of the com plete device, showing the neer rear carrier Wheel removed. Fig. 2 is a plan View oi the complete eilevice. Fig. 3 shows a side elevation of tivo of the brush ctions and their connecting' joints.' lig. gl'is an end View a' section oit' the brush, showing portion of the end of its hood broken away. Figs. 5 and (l show elevational .side and edge, viens respectively, of the brush supports, and if' and 8 show elevational sidejand edge views. resj'ieci'ively, of the racleanddog' a fane'einent., Whirh controls the elevatiing Windla i.

Referring non' more particularly to the diraniensi wherein like numerals of. reference designate similar parts in each oi the igures.,

'the nuine al 1 designates the frame-Work of the sweeper, which is carried on front and fear carrier Wheels designated7 respeetively,V by the numerals 2 and f3. The device is pro-l vided with a motor' (not shou'nl'f of' the character ot he ordinary automobile, which is operatively connected in the usual manner with tl ear ordriviiigr wheels-f3, bij* means eiC sprocket chainsv 4, 1, andthe sprocket,

wheels 5, the latter of Which areearried tij: the driving wheels 3 3, which are mount.- ed upon the axle 6. Through the mechanism thus described the sweeper may be moved from place 'to place over the street. or other surface soughtl to be cleaned. The side ineinliers ofthe traine-wml: 'l project some distance rearwardlyv bevond the rear axle (l. and the rearwardly projecting; portions are provided with thehinges T, and arms ll are' united bj' said hinges to said members and. consequently. muv be moved up and down relative to the stationaryY portion ol' :the ierainefworli, and fixed to said hinged poi tions 1L are depending rsupports 87 S. and;

51. if). whose loiver ends have oblong rerti-fA call)7 extending slots, in which are mounted sliding bearings 10 and 1l5 for a purpose to brhereinafier Set forth.

AThe numerals 12 and|13, v respeetively.`

designate shafts alpen V'which'. cylindrical brushes 14 vand 15, respectively, are mounted. rlliese brushes are formed in sectioi'isfand the shafts 12 fand 13 have universaljoints be;

tween the respective brush sections, as shown in Vlig. 3v.' so as to make the brushes practically liexibleTand the brush 14 is arranged u in frontoif the brush 1 5, the sections of the -fornier being' arranged in staggered relation imam-sanno; 5, rois.

that any refuse which may esc-apebetween l the sections of lthe former will be gathered up by the latter. The brushes are formed in sections and the shafts thereof are made flexible so that said brushes will readily con forni to the uneven or convex surface of the,

street,;and all the ivaste and refuse .matter i thereon ivill be gatl'ieredup. The brush see tions are `inclosed above and in front and rear by means of inelosing hoods 16 and 17,

which have inclosed ends 18 and 19, the ends beingA provided with bearings through which the respective shafts 12 and 13 extend, and

the hoods are thus secured in xed positions ,relative to the brush sections.

The under sides. of the hoods are open so as to expose the brushes and permit them to Contact With the surface to be cleaned.y Leading from the 1 top portions of the'hoods 16 and 17 are conveying pipes 20' and 21, formed .of flexiblev These conveying material fsueh as rubber. pipes discharge into a receivingdruni .fixed upon the rear portion of the frame- Work '1,

lvlounted upon the supporting frame are taclesl 2l. 23,- and their discharge ends are curved downwardly, as shown in lFigc/1, so as to direct the refuse ldown toward the bottom of the receptacles. Each receptacle 23, 2:3 has a discharge refuse may be discharged into an independent conveyor. in case it is not desired to `burn the same as hereinafter set forth.

Underneath the .receptacles 23,23,and arranged between them, is a furnace 26, into which tbe refuse may be discharged tlirough the trap doors 27, 27. and wherein said refvuse may be burned, 4thc unconsumcd portion the discharge ends of the conveyers 24, 24,-v

to the end that the refuse discharged into the said receptacles will not be caught up and 'conveyed through said pi es. It is obvious that the suction create by the fans 29, 29, willcxtend through the various conveyer pipes 20, 21,-and 24, and will operate to suck up the refuse delivered from the brushes and discharge the same into the refuse receptacles 23, 23. l

The rear axleG of the device has a cen- -trally located rigidly mounted pulley Wheel 32, and mounted .in suitable bearings'33,-33, carried by thc arms l is a transverse Shaft 34, which has a centrally located, loosely mounted pulley wheel 35, which receives ro- ,ftation through thc belt 36 from the pulley :32. This shaft 84 has also`rigidly mounted sprocket: wheels 37, 37,.onc located on .each side of the pulley and these wheels drive the brush 14; through sprocket chains 38, 38, which are operatively connected with corresponding sprocket wheels 39, 39, rigidly mounted on the shaft 12 and between the sections'thercof. Rotatably mounted in 'suitable bearings Avl0. 40, carried by the arms l, is a transverse shaft 41. This Shaft is driven by sprocket chains 42, 42, which are, in turn., driven by the sprocket wheels 43, 43, 'rigidly mounted upon the shaft 34, and which drire said shaft 4l through the sprocket wheels' 44, 44, rigidly mounted upon the shaft /1-1. The shaft 41"'also carries rigidly mounted sprocket wheels 45,45, and drive the'sprocket chains 46, 46, which are, in turn, operatively connected with sprocket. wheels 47, 47, rigidly mounted upon the. shaft 121. bet wenn vthe end sections of the brush 15. The shafts 12 and 13 are mount- 25, through which thev ed in the sliding bearings .10 and ll of the supports S, 8, and tl, t), and thebruslics are h'eld yieldingly against the surface-by means of strong coil springs 48, 48,` and 4t), 45t, which are secured to the respective supports S, S, and 9, il. at their respective upper ends, and whose lower ends resistagainst the bearings 10 and 11. The under portions of the hoods 1S and 19, immediately in liront of the brushes, carry flexible aprons 5l). 5t), and 51,'51, whose free edges extend to the st reet surface, and these aprons catch up the refuse delivered from the brushes and hold it until it is caught up by the suction through the 4crmvejviug tubes. A windlass 52 is provided.a1ul attached to the extreme rear end of the trame-work 1, on Acach side, are strong cables 53,53, and by means of this windlass the hinged portion of the fraine-\\'o1k and the brushes and their 0perative mechanism may be elevated, and the brushes thus lifted from contact with the surface being swept, as will be desirable.

when it becomes necessary to move the device from place to place. vEach end of the windlass has a rigidly mounted ,ratchet wheel 54, 54, and pivoted to each bearing 55, 55, in which the windlass is mounted,

is a dog 56, 56, which may be made to en-4 gage with the teeth of the ratchet wheels 54, 54, and the windlass secured against rotation, a-nd the vbrushes thus held at any point of elevation desired. The pulley Wheelf is arranged to bel clutched with and declutehed from its shaft 34 when desired by means of clutch 57, so that the operation of the brushes may be stopped at will.
